Air Sentry Shock-Resistant Dessicant Breather 5.2 inch (W) x 6.5 inch (H) - 1 inch MNPT

In any reservoir containing fluids or semi-solids, air is breathed in and out as the fluid level changes or as thermal expansion and contraction occurs. Fluid contamination is the primary cause of component wear and lubricant failure in industrial equipment.

Air Sentry breathers replace the standard breather cap or vent tube on a tank of reservoir. They are easy to install using one of several adapters designed for different applications.

When the fluid in the system is lowered, or pressure changes occur, air is drawn in through openings under the breather cap. First, air passes through a fine, 2 micron solid particle filter. The air then passes through a diffuser to ensure maximum effectiveness within the silica gel chamber.

Next, water vapor is removed as the air travels through a bed of silica gel - the highest capacity adsorbent available. After being dried, the air passes through a second 2 micron solid particle filter and enters the reservoir clean and dry.

Air Sentry breathers use a three-stage filtration design to ensure optimum protection by removing water vapor and solid contaminants before they enter the fluid system.

Air Sentry® R-Series Contamination Control Breathers were designed in conjunction with a major United States railroad company to withstand continuous heavy vibration and are used on applications such as railroad maintenance equipment, off-road vehicles, and mining equipment. The units are easily attached to the equipment by rugged steel pipe threads.

The metal reinforced base of the unit remains on the gearbox or reservoir and a replacement cartridge is easily screwed into the base. The R-Series Breathers are attached to the reservoir, gearbox, or tank by 1" (Models R-100, R-101 and R-102) or 2" male pipe threads (Model R-123). The R-111 has a female threaded mounting hole for attachment to certain pressure regulating valves.

• Height: 6.5 in / 16.5 cm
• Diameter: 5.2 in / 13.2 cm
• Weight: 3.2 lb / 1.45 kg
• Maximum H2O capacity: 6.2 fl.oz
• Nominal Air Flow Rate: 35 CMF (990 L/min) Equivalent of 260 gpm of fluid volume change
• Solid Contaminant Filtration Level: 2 micron, 100% efficiency @ 35 CFM air flow
• Operating Temperature Range: -20° to 200°F / -28° to 93°C
• Silica Gel Adsorption: Up to 40% of its weight of water
• Silica Gel Lowest Operational Dew Point: -100°F / -73°C
• Chemical Resistance: Resistant to alkalis, hydrocarbons, non-oxidizing acids, salt water and mineral or synthetic oils

• Bi-directional Air Flow - Air entering is cleaned and dried. Expelled air partially regenerates the silica gel and "backflushes" the particulate filter to prolong the life of the breather.
• Durable Construction - Air Sentry is manufactured from rugged ABS plastic and impact-modified Plexiglas.
• Water Vapor Adsorbent - The silica gel used in Air Sentry breathers is chemically inert, non-corrosive, and conforms to all regulated toxicity standards in the U.S. and other countries. Microscopic pores allow the silica gel to adsorb up to 40% of its own weight.
• Color Indicator - When maximum adsorption is reached, the silica gel turns from gold to dark green to indicate that replacement of the breather is required.
• Activated Carbon - As air is expelled from the tank, it passes through activated carbon which remove oil vapors, fumes, and odors.
• Safety Sealed - Seals keep moisture from entering the units until they are placed in service. They are easily removed without tools or sharp instruments.
